OlL-RECEPTAQLE.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed December 27, 1904. Serial No. 238,331.

the following is a specification.

This invention relates to an improved oilreceptacle which is soconstructed that the oil can always be drawn from the reservoir at apoint slightly below the varying level of the oil, so that the sedimentsand impurities settling upon the bottom remain undisturbed.

In the accompanying drawings, Figurel is a vertical section of myimproved oil-receptacle; Fig. 2, a plan thereof, and Fig. 3 a detail ofthe telescoping pipes.

The letter A represents a'delivery-tank provided with an oil-pump b, thesuction-pipe of which is operatively connected by a branch 6 with thelower end of an outer inlet-pipe r. This pipe telescopes an innerrotatable inlet-pipe a, which is provided with a series of perforationsor slits Z, arranged in a vertical row. The outer pipe '2' hasperforations or slits arranged in a spiral, so that by giving the pipe(0 a slight turn any one pair of perforations l 0 which are in the samehorizontal plane may be made to register. In

this way there may be formed an oil-inlet directl y below the level ofthe oil B, and this inlet may be lowered as the level falls by thewithdrawal of the oil from the reservoir. By operating the pump the oilis drawn from the reservoir through the registering inlet-openings 0 Zinto the inner pipe at and thence through branch pump 6, and exit-pipe cto the discharge-nozzle c, that carries the oil out of tank A. In orderto ascertain the elevation of the inlet, the inner pipe (4 carries apointer 2, moving over scale s.

lt is obvious that in lieu of the construction described theperforations in pipe 0' may be arranged in a straight line and those inpipe (0 in a spiral or the two sets of perforations may be arranged inopposing spiral lines.

What I claim is An oil-receptacle composed of a deliverytank, an innerrotatable perforated pipe Within the same, an outer telescoping pipehaving spirally-arranged perforations, and a pump operatively connectedto the bottom of the outer pipe and adapted to draw the oil through saidpipe and out of the tank, substantially as specified.
